<H1>About pop-up windows</H1>


Pop-up windows are based on an <a href="str_hh_popup.htm">HH_POPUP</a> structure and include the following default properties: 
<ul>
<li>The pop-up window is positioned relative to the mouse. The calling program can override this with a specific position.
 
<li>The width and height of the pop-up window are determined by the amount of text. The help author or the program can specify an exact width or height.
 
<li>If there is insufficient screen real estate to display the text, the text is clipped. A pop-up window never includes a scroll bar. 

<li>The pop-up window is dismissed when the user clicks inside or outside the window, presses <code>Esc</code>, or when the pop-up window loses focus.</li>
</ul>
